Mercy Hospital St. Louis Named 100 Top Hospital for Sixth Time

March 5, 2018

ST. LOUIS – For the third consecutive year and sixth time, Mercy Hospital St. Louis was named one of the nation’s 100 Top Hospitals® by IBM Watson HealthTM, formerly Truven 100 Top Hospitals. The quality care at Mercy Hospital St. Louis has been repeatedly recognized in recent years including being named a CMS Five-Star Hospital, a Leapfrog Straight A Hospital and a Leapfrog Top Hospital.

“This award, alongside other recent national recognition, places Mercy Hospital St. Louis among the very best hospitals across the country," said Steve Mackin, president of Mercy Hospital St. Louis. "It’s validation of the work our Mercy team does every day to serve our patients.”

The study, conducted since 1993, spotlights the top-performing hospitals in the U.S. based on a balanced scorecard of publically available clinical, operational and patient satisfaction metrics and data.

The Watson Health 100 Top Hospitals® study uses independent and objective research to analyze hospital and health system performance in 11 specific areas. Following were the key performance measures on which 100 Top Hospitals outperform:

  • Better survival rates
  • Fewer complications and infections
  • Shorter length of stay
  • Shorter Emergency Department wait times
  • Lower inpatient expenses
  • Higher patient satisfaction

Based on the results of this year’s study, if all Medicare inpatients received the same level of care as those treated in the award-winning facilities:

  • More than 102,000 additional lives could be saved
  • More than 43,000 additional patients could be complication-free
  • More than $4.4 billion in inpatient costs could be saved
  • Approximately 200,000 fewer discharged patients would be readmitted within 30 days

“The country’s best hospitals have proven that an unrelenting focus on quality, supported by constant measurement against peer performance benchmarks, can drive improved outcomes while reducing costs and growing profit margins,” said Jean Chenoweth, senior vice president, 100 Top Hospitals Programs, IBM Watson Health. “Congratulations to this 25th anniversary class of 100 Top Hospitals who have helped raise the bar for healthcare in the U.S. and improve the healthcare experiences of the people in their communities.”

The winning hospitals were announced in the March 5, 2018 edition of Modern Healthcare magazine. Mercy Hospital Oklahoma City was also named to the 100 Top Hospitals list. In addition, Mercy, as a system of hospitals across four states, has been named a 15 Top Health System for two years in 2016 and 2017.
